I have a 1964 Williams Soccer Pinball machine and I'm working on refurbishing it. I've replaced all the rubber rings but there is an electrical problem that I cannot diagnose. Where does one find a pinball repair person? I live in Roanoke, VA. I found a few pinball repair enthusiasts, but they're in PA, MI, and IL - too far. Would an regular electrician know what he's doing? All I'd want is a diagnosis of what part needs to be replaced.
